While a '-' alone isn't strictly valid it hadn't previously cuased a
|
|
|
cd8711 |
parse error. So commit 9047e91ffa69 (autofs-5.1.7 - fix concat_options()
|
|
|
cd8711 |
error handling) introduced a regression by no longer allowing this.
|
|
|
cd8711 |
|
|
|
cd8711 |
Fix this regression by only failing if errno is set to a non-zero value
|
|
|
cd8711 |
on return from concat_options() as well as returning NULL.
